引言
AWR提供了多种传输线模型，如何根据实物选择合适的模型，是仿真结果正确与否的关键。从官方帮助文档中，我们可以看到AWR包含了如下这么多的传输线模型。
在选择模型时，了解每种传输线的特性是非常有必要的。本文并无深刻内容，仅仅是官方文档的翻译和整理，用于笔者自己查阅方便，若想快速了解AWR中传输线模型的基本概念，可以参考本文。
Phase Spec: Coupled Lines (Closed Form): CLIN
CLIN 模拟一对对称耦合的无损传输线，该传输线支持纯 TEM 模式传播。该模型假设传输线长度以用户指定频率下的电长度（沿传输线传播模式的相位滞后）来定义。用户必须提供奇模和偶模特性阻抗的数值。
